On his 74th birthday, a man got a gift certificate from his wife.
The certificate paid for a visit to a medicine man living on a nearby reservation
who was rumored to have a wonderful cure for erectile dysfunction.
After being persuaded, he drove to the reservation,
handed his ticket to the medicine man and wondered what he was in for.
The old man slowly, methodically produced a potion, handed it to him,
and with a grip on his shoulder, warned,
"This is powerful medicine and it must be respected.
You take only a teaspoonful and then say '1-2-3'.
When you do that, you will become more manly than you have ever been in your life
and you can perform as long as you want."
The man was encouraged. As he walks away, he turned and asked,
"How do I stop the medicine from working?" "Your partner must say '1-2-3-4,' he responded,
"But when she does, the medicine will not work again until the next full moon."
He was very eager to see if it worked so he went home, showered, shaved,
took a spoonful of the medicine, and then invited his wife to join him in the bedroom.
When she came in, He took off his clothes and said, "1-2-3!" Immediately, he was the manliest of men. 
His wife was excited and began throwing off her clothes. And then she asked, "What was the 1-2-3 for?"

And that, boys and girls,
is why we should never end our sentences with a preposition, because we could end up with a dangling participle.

A good reason to watch the grammar.

ROFLMBO!

The importance of proper capitalization is the difference between helping your Uncle Jack off a horse & helping your uncle jack off a horse!

Either way, I think the horse wins.
